Jack-It's lead mechanic, Kyle Boddy, is shown installing one of the upper tubular link arms for the front suspension. These links are made from 1.5-inch DOM tubing and feature extra-long tapered weld bungs and a durable powdercoat finish. The extra bung length ensures that the joints will have plenty of thread engagement while also allowing gobs of adjustability. The lower portion of these links includes fully welded bolt tabs that attach to the top of the axle assembly. The lower ends of these links employ durable polyurethane with zinc-impregnated bushings. The chassis-side of the upper link arms features Trail Master's rebuildable flex joints to provide years of noise-free operation. The lower link arms are very similar except for the fact that they are manufactured from 2-inch DOM tubing and use a flex joint at each end.
